purple throbber

A penis that is so errect that it turns purple and throbs.

I stuck my purple throbber in your mom's ass lastnight and she screamed like a sheep in a slaughter house.

purple headed throbber

A raging hard-on...ready to explode

She rode me until she climbed off my purple headed throbber and it spayed all over her face
